where did you get fittings for PE pipe?

I am replacing a main water line with 1 inch PE pipe.
I have looked in several stores for fittings and all i can find are the steel fittings below.
And all they have are the standard hose clamps, like the ones in cars to hold them on.

The PE pipe is pretty stiff and I'm wondering if the hose clamps will work.
Are there some other kind of fittings to use on PE pipe?
If so, where do you buy them? any online sources?

If your dealing with PE, mostly we use Philmac compression fittings. Very easy to use and it's rated for underground use. note: If philmac is not sold in your area, sharkbite is rated for underground but its not the first product I buy. try and find a similar compression fitting like Philmac.

Normally when working with PE one buys a big enough reel so that only one length of pipe is required for the job. This eliminates the need for any buried fittings. I don't trust plastic pipe fittings, especially threaded fittings, but have never had an issue with the stainless steel ones which are readily available.
